Distillation column pressure variation can increase column capacity. Capacity gains can be achieved either from raising or lowering the pressure. Raising the pressure reduces gas density, thus allowing a greater vapor flow rate through the column, but it also reduces relative volatility, causing a higher reflux and reboil requirement for the same separation. Research and describe a scenario where applying a pressure variation to a distillation column might be preferable

For the earth, a reasonable estimate of the variation of pressure with altitude can be made for a gas of molecular weight, M, assuming the atmosphere is isothermal, the variation of g with altitude is negligible, and that the atmosphere behaves like an ideal gas. (a) Under these assumptions how does the pressure vary with altitude in terms of the altitude, y, molecular weight of the gas, M, gas temperature, T, and appropriate constants? (b) How does the number density...

There are many avenues that companies can use to increase their capacity. Some are more permanent (hard ceiling capacity increases) some are more temporary (soft ceiling capacity increases). Suppose that you are running a company that produces a component for the automotive industry. Your current capacity is 5,000 units per week. You have calculated that you will need to increase your capacity to 7,500 units a week to meet your current demand. You are considering the following methods of increasing...
